I read a sci-fi book several decades ago in which the monetary unit had (in the future) become the Chicle - after the chicle gum on which original chewing gums were based. Evidently the author theorized that the relative worth of chewing gum was stable against the worth of other "things". Anyone remember the book?Cop Car

"A chicken will lay bigger and stronger eggs if you change the lighting in such a way as to make them think a day is 28 hours long."

Am I the only one who interprets this to mean that they are elongating the day from 24 hours to 28 hours, but that the chickens are given a "daylight" part and a "nighttime" part of those 28 hours? I don't think there is any harm to the chickens.

In fact (and I'm not researching this, so please don't shoot me if I remember incorrectly), I think that researchers established that a 28-hour (more or less) day is more natural for humans - inferring that the days were longer during earlier stages of evolution of all animals now on earth?Cop Car
